I think RNs should be allowed to intubate if they're trained. 20+ years ICU-CCU and ER, both in Level 1 and 2 trauma centers. It's 3 am in ICU, you have a problem with the ET tube, you should be able to replace it. I also understand the liability associated with same. Guess it boils down to where one works. If your anesthesiologist, anesthetist is right down the hall, then call them. I don't see a need for a med-surg staff RN to do it as they lack the frequency in placement. As an RN we put in art lines. If we can put in an art line, we can put in an ET tube. I've seen some RNs who had to call the med student to replace/start an IV if they're in a teaching hospital.
